Q:Friends to learn to drive roller,

Do you want to open what is the single roller, Ganglun repair pavement or asphalt pavement temperature, double rigid gear

Q:What's the inner structure of the roller?

Single axle shaft type generally used in small vibratory roller, can achieve a single or two amplitude; and the shaft shaft type generally used for large and medium-sized vibroll, you can achieve multiple amplitude; welding disc plate and detachable box is widely used, but the detachable box compared with welding disc plate, the cleanliness of the oil chamber and the bearing hole concentricity is easier to achieve, can improve the service life of the bearing vibration.

Q:What are the working conditions of impact rammer,

The following is the analysis of these equipments for you:Roller: both compacted asphalt and cohesive soil can be used.Flat rammer: sand granular media, such as sand, asphalt (with sprinkler device).Impact rammer: sticky soil, requiring high pressure and solid occasionsDifference between compacting equipment:The roller is compacted by its own weight and exciting force, and the roller is in line with the ground compaction medium.
